Question

give reasons sameer's heart beat rate is 76/min at rest after jogging his pulse rate is 98/min​

Answer 1

When Sameer goes for jogging, more work is done by the cells of the body and hence more energy is required by the cells of the body. Energy can be obtained by the process of respiration and requires oxygen. Hence jogging causes an increase in the oxygen demand. Oxygen is supplied through the blood which is circulated throughout the body by the pumping of the heart. Hence to fulfill the increased oxygen demand by the body, the heartbeat of Sameer increases during jogging.
